Theresa May could be forced out by the end of June if she fails to deliver a Brexit deal

THERESA May could be axed as Prime Minister by the end of June if she fails to secure a Brexit deal, sources claim.

Tory insiders say a new vote of no confidence is inevitable if talks break down.

Sources said the PM will be given marching orders by the “men in grey suits” unless it’s clear by the end of next month that her plan has a chance of succeeding.

The revelation comes just days after the powerful 1922 Tory backbench committee voted 9 to 7 against ripping up party rules to allow a new no confidence challenge against the PM this summer.

In his Sun column today, James Forsyth reveals 1922 chair Sir Graham Brady will ask the PM for more clarity on her departure plans again next week.

And insiders believe he will warn that a rule change to allow a new no confidence vote is all-but inevitable without progress on Brexit.

JUST WEEKS TO 'PULL A RABBIT OUT OF THE HAT'

One 1922 member said: “You won’t keep this at bay forever.

“But she has a few more weeks to pull a rabbit out of the hat.”

The revelation comes as Cabinet Ministers fear the European Elections are unavoidable given the Brexit logjam in Parliament.

One called on the PM to go back to the Commission to ask for a fresh commitment to a technological solution on the Irish border by the end of 2020.

Downing Street has set an absolute deadline for a Commons deal on Brexit of June 30 – the last possible day to prevent MEPs taking their place in the European Parliament.

But they fear talks with Labour will continue to drag on as there is no immediate incentive for Jeremy Corbyn to thrash out a compromise.

LABOUR NOT WORKING FOR PM

One source said: “Labour will want Brexit sorted by the time of the party conference so they can avoid a big row about a referendum.

“But that means they don’t have any incentive to act until September.

“We need something long before then.”

The Sun yesterday revealed Sir Graham had urged the PM to support a fresh bid to strip out the Irish backstop from her EU deal.

Tory Eurosceptics want the backstop – a customs plan designed to avoid a hard border in Ireland – taken out of the withdrawal agreement when it goes before Parliament in a bid to win a majority.

They want to write in a commitment by both the UK and EU to introduce “alternative arrangements” such as hi-tech cameras.

But the move would spark a huge row with the EU. Leaders of its 27 member states are adamant the backstop has to be part of Mrs May’s deal.
